Double hits/ Double spell casts on last hit on mobs?
 

Greetings, I've looked and I didn't see this posted, pardon if this has already been posted. I took a 6 month break, came back, started grouping and I noticed I got the last hit and kill on a monster, to my surprise it looked like I double backstabbed the monster as a level 49 rogue.

While asking I was told in group this happens on the last hit of a fight, its a visual bug were you see the same exact hit twice like:

You backstab soandso for 149 damage!
You backstab soandso for 149 damage!
you've slained so and so..

Any suggestions?

Just a double message. Sorry, not actual double damage. Should be fixed next patch.
